Anyone seen this before? I spent a week trying to track down the source of packet loss. I have a chain of 4 towers all linked together with Airfiber 5x's and an RB 3011 at each site connected via OSPF. I was seeing 1% packet loss on each link, so 4% by the time we got to the end of the chain. I spent most of my time troubleshooting airfibers thinking they were the problem, but I got desperate and started trying random things. Turning off the LCD displays on each router solved the problem! Once I disabled them the packet loss instantly went away, and I mean instantly! I'm wondering if the display doesnt emit some type of interference into the ethernet ports. I had mine set to always on with no backlight timeout and they were set to change every 1 min to informative slide show.
I can turn the lcd back on and within a few pings causes loss again.
Weird huh?
